2024-07-17power: sequencing: fix an invalid pointer dereference in error pathBartosz Golaszewski
We may end up calling pwrseq_target_free() on a partially initialized target object whose unit is either NULL or an ERR_PTR(). Avoid dereferencing invalid memory by adding an appropriate check to pwrseq_target_free().

Building the fbnic nn s390, yield a build bug: In function ‘fbnic_config_drop_mode_rcq’, inlined from ‘fbnic_enable’ at drivers/net/ethernet/meta/fbnic/fbnic_txrx.c:1836:4: ././include/linux/compiler_types.h:510:45: error: call to ‘__compiletime_assert_919’ declared with attribute error: FIELD_PREP: value too large for the field The relevant mask is 9 bits wide, and the related value is the cacheline aligned size of struct skb_shared_info.

2024-07-17s390/mm: Fix VM_FAULT_HWPOISON handling in do_exception()Gerald Schaefer
There is no support for HWPOISON, MEMORY_FAILURE, or ARCH_HAS_COPY_MC on s390. Therefore we do not expect to see VM_FAULT_HWPOISON in do_exception(). However, since commit af19487f00f3 ("mm: make PTE_MARKER_SWAPIN_ERROR more general"), it is possible to see VM_FAULT_HWPOISON in combination with PTE_MARKER_POISONED, even on architectures that do not support HWPOISON otherwise. In this case, we will end up on the BUG() in do_exception(). Fix this by treating VM_FAULT_HWPOISON the same as VM_FAULT_SIGBUS, similar to x86 when MEMORY_FAILURE is not configured. Also print unexpected fault flags, for easier debugging. Note that VM_FAULT_HWPOISON_LARGE is not expected, because s390 cannot support swap entries on other levels than PTE level.

2024-07-17virtio_pci_modern: use completion instead of busy loop to wait on admin cmd ↵Jiri Pirko
result Currently, the code waits in a busy loop on every admin virtqueue issued command to get a reply. That prevents callers from issuing multiple commands in parallel. To overcome this limitation, introduce a virtqueue event callback for admin virtqueue. For every issued command, use completion mechanism to wait on a reply. In the event callback, trigger the completion is done for every incoming reply. Alongside with that, introduce a spin lock to protect the admin virtqueue operations.

2024-07-17virtio: create admin queues alongside other virtqueuesJiri Pirko
Admin virtqueue is just another virtqueue nothing that special about it. The current implementation treats it somehow separate though in terms of creation and deletion. Unify the admin virtqueue creation and deletion flows to be aligned with the rest of virtqueues, creating it from vp_find_vqs_*() helpers. Let the admin virtqueue to be deleted by vp_del_vqs() as the rest. Call vp_find_one_vq_msix() with slow_path argument being "true" to make sure that in case of limited interrupt vectors the config vector is used for admin queue.

2024-07-17ALSA: seq: ump: Skip useless ports for static blocksTakashi Iwai
When the UMP Endpoint is configured with static blocks, the block configuration will never change, hence the unused ports will be unchanged as well. Creating sequencer ports for those unused ports is simply useless, and it might be rather confusing for users. The idea behind the inactive ports was for allowing connections from/to ports that can become usable later, but this will never happen for inactive groups in static blocks. Let's change the sequencer UMP binding to skip those unused ports when the UMP EP is with static blocks.

2024-07-17dt-bindings: mtd: qcom,nandc: Define properties at top-levelRob Herring (Arm)
Convention is DT schemas should define all properties at the top-level and not inside of if/then schemas. That minimizes the if/then schemas and is more future proof. There were 2 "if" schemas for "qcom,ipq806x-nand" and the "qcom,boot-partitions: true" unnecessary, so the conditional schemas can be simplified a bit.

2024-07-17mtd: rawnand: intel: use 'time_left' variable with wait_for_completion_timeout()Wolfram Sang
There is a confusing pattern in the kernel to use a variable named 'timeout' to store the result of wait_for_completion_timeout() causing patterns like: timeout = wait_for_completion_timeout(...) if (!timeout) return -ETIMEDOUT; with all kinds of permutations. Use 'time_left' as a variable to make the code self explaining. Fix to the proper variable type 'unsigned long' while here.

2024-07-17mtd: rawnand: gpmi: add iMX8QXP support.Han Xu
Add "fsl,imx8qxp-gpmi-nand" compatible string. iMX8QXP gpmi nand is similar to iMX7D. But it is using 4 clocks: "gpmi_io", "gpmi_apb", "gpmi_bch" and "gpmi_bch_apb".

2024-07-17mtd: rawnand: gpmi: add 'support_edo_timing' in gpmi_devdataFrank Li
Introduce a boolean flag, 'support_edo_timing', within gpmi_devdata to simplify the logic check in gpmi_setup_interface(). This is made in preparation for adding support for imx8qxp gpmi.
